Abstract: Terminal device attempts to initiate a COT-u after the channel is sensed to be idle and transmit a configured grant PUSCH. A start of a time domain resource of the configured grant PUSCH is aligned with the start of the FFP-u. In a case that the FFP-u does not overlap with an IP-g of an FFP-g, the COT-u is initiated and the configured grant PUSCH is transmitted.

Abstract: Terminal device attempts to transmit a PUSCH scheduled by a DCI format after the channel is sensed to be idle. When the start of the PUSCH is not aligned with an FFP-u, in a case that the channel access mode is configured to as semi-static, the terminal device does not initiate a COT, regardless of indication by a ChannelAccess-CPext field in the DCI format.
